Permagloss Permanent Tire Protectant is unlike any other tire dressing or tire shine product on the market. First, Permagloss provides a rich, glossy shine that can last the entire life of your tires ⦠a feat no other product has ever achieved. Instead of the weeks, months or â100 Washesâ that other premium tire shine products propose to deliver, a single application of Permagloss Permanent Tire Protectant can continue to shine and protect virtually forever, while withstanding conditions that would obliterate most other tire appearance products.
